Atlas designed their 12 Series Snowshoes specifically for backcountry denizens like mountaineers and snowboarders who have larger boots and require maximum floatation, traction, and ankle articulation. The ergonomic, versatile ratchet-buckle bindings are easy to get on and off and accommodate large volume boots. Atlas' patented Spring-Loaded suspension returns 10lb of energy with each step and maintains your natural ankle articulation while eliminating heel rotation, so you use less energy and maintain a stable, secure stride over difficult terrain. Stainless steel All-Trac toe and heel crampons and Traverse Trac side rails offer reliable traction over varied terrain, descents, ascents and traverses. Made from strong, lightweight Easton 7075-T7 aluminum with durable Duratek decking material, the 12 Series make getting to the summit a lot easier. Bottom Line: The approach doesn't have to be a slog.
